Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472506, here are decompositions:

5 + 31472501 = 31472506
17 + 31472489 = 31472506
167 + 31472339 = 31472506
347 + 31472159 = 31472506
353 + 31472153 = 31472506
383 + 31472123 = 31472506
503 + 31472003 = 31472506
599 + 31471907 = 31472506

Showing the first eight; more decompositions exist.
